Question

What makes the equation not quadratic? Differentiate a quadratic equation
from an equation that is not quadratic.​

Answer 1

$Hii$

1. What makes the equation not quadratic?

=> Examples of NON-quadratic Equations :

bx − 6 = 0 is NOT a quadratic equation because there is no x2 term. x3 − x2 − 5 = 0 is NOT a quadratic equation because there is an x3 term (not allowed in quadratic equations).

2. Differentiate a quadratic equation  from an equation that is not quadratic.​

=> A quadratic function is a function of a single variable x, with a value y determined by a formula of the form: y = ax^2 + bx + c, where a, b and c are constants. On the other hand, an equation is a mathematical statement saying that something is equal to something else.

Answer 2

The answer to the question as to what makes the equation not quadratic will be:

• An equation is claimed to be not quadratic when there are more than two solutions in an equation that satisfy it. Basically, the absence of the square term in the equation makes it non-quadratic. If there is an equation $x^2-16$ it has two solutions $+4$ and $-4$.

To differentiate a linear equation from a quadratic equation:

• If we try to plot the graph of a simple linear equation and a quadratic equation, we will see the linear equation creates a straight line while the quadratic equation creates a parabola on the graph. Moreover, there are two solutions or roots to a quadratic equation that satisfy it while there is only one solution to a quadratic equation.
